Question about 1998 GMC Jimmy
You need to get or rent a coolant system tester and identify where it is leaking from. They are very simple to use. You just remove your radiator cap and install the tester and pump up the cooling system and then you watch for where the coolant is coming from. Look closely at your water pump, intake manifold gasket, radiator, heater hose coupler on the intake manifold, and coolant hoses. Those are all the common leak areas.
